RUDOLPH CONRADER, OF ERIE, PENNSYLVANIA.

To all whom` t may concern.'

Be it known that l, RUDOLPH CONI-morn, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Pumps, of which the following is a specification.

This invention relates to pumps, and consists in cert-ain improvements in the construction thereof, as will be hereinafter fully described and pointed out in the claims.

Among the objects of the invention may be mentioned, the pulling of the standing valve with the plunger; a working barrel which will vterm a bypass around the stand ing valve when the standing valve is lifted into the barrel so that liquid above the standing valve may pass downwardly, thus cleaning the pump; the lifting of the standing valve with the plunger with an arrangement of parts whereby this is accomplished without pulling the plunger out of the working barrel; the opening of the standing valve so that the liquid above the plunger may pass through the plunger and past the standing valve when lifted; and a rod actuating device secured to the trunnion of the walking beam for actuating the plunger be` yond its normal movement for the purposes above described.

Other details oi the invention will be shown in the specification and claims.

My invention is illustrated in the accompanying drawings as follows:

valve socket G in which is arranged the standing valve 7, the standing valve having the usual packing S for making a oint with the socket. The standing valve has the crown 9 in which is arranged the check 10.

The plunger 11 is provided with the usual plunger cups 12. It has the central open ing 13 which is closed by the check 15 arranged in the crown 16. A sucker rod projection 17 is secured to the crown, and the sucker rod 1S secured to the projection. The sucker rod terminates in the polished rod 19.

The standing valve crown 9 has an extension 2O with the sides 21, the upper transverse portion 22. A bolt 23 extends through the transverse portion 22, and the head of the bolt 24 slides between the sides 21, the sides locking the bo-lt against turning relatively to the standing valve. A spring 25 is tensioned against the bolt and the top ot' the crown oi the standing valve. The projection 26 on the crown of the standing valve and on the `head of the bolt holds the spring in place.

Thelower end of the plunger is screw threaded at 27 and the fitting 28 has the collar 29 which is internally screw threaded and screwed onto the bottom oi' the plunger, the collar forming a nut for holding the cups iu place. 'lhe passages 30 lead into the tting and to the passage 13 in the plunger. The Fitting has the downwardly extending projection 31 in which there is a screw threaded opening 31a adapted to be screwed onto the bolt 23.

Heretotore, the standing' valve has been coupled with the plunger by means of a screw, the plunger being lowered and turned so as to screw the parts together. The dil'l'iculty with this arrangement has been that it was so ditlicult to so control the plunger that the screws could not be brought into engagement 'without jamming' the threads so as to prevent the entering oit the screws. Viith this invention as the plunger lowered, the bolt Q3 yields (see Fig. so as to prevent any serious impact between the pliilnger and the bolt. At the same time, the spring exerts such pressure on the bolt as to assure its entering the screw threaded opening 31d the plunger is turned, (see Fig. 8). The bolt preferably has suiiicient movement that the projection 31 will reach the top of the extension 2O before reacl'iing the limit of movement of the bolt as clearly shown in Fig. 5.

It is desirable to have the enlarged portion o-f the working barrel 2 of suiiicient length to permit the lifting of the standing valve so as to bring it into this enlarged portion, thus forming a bypass around the standing valve so that the liquid can discharge in order to clean the pump, and also for the purpose of cleaning the tubing as a preliminary to pull-ing the sucker rods. It is often desirable to get this flooding, and it is also advantageous to accomplish this without lifting the plunger from the working barrel. IVith the present construction, th'e plunger is lowered and turned so as to effect the coupling of the plunger with the standing valve and lifted, and it is still in the working barrel when the standing valve reaches a position in the enlarged portion so as to form the bypass (see Fig. 7

To facilitate the discharge of liquid from above the plunger, it is desirable to force the plunger valve open so that the liquid may pass through the plunger. A push pin 32 extends from the top of the bolt 23, and is of suiiicient length so that when the bolt 23 is screwed into' the screw threaded opening 31, the push pin 32 will force the valve 15 to an upper position as shown in Fig. 8. This then leaves a free passage for the liquid through the plunger.

In order to easily lower the plunger to a position where it will engage the standing valve, and to lift the standing valve, I prefer to provide a sucker rod actuating device in connection with the trunnion operating on the walking beam or other reciprocating device. A polished rod 19 extends through the polished rod adjuster 33, the polished rod adjuster has the eye bolt 34 with the screw projection 36 and the nut 37. By screwing up the nut, it will be readily seen that the eye bolt will be drawn sidewise so as to clamp the polished rod in adjustment as desired. This in the main is the ordinary construction of polished rod adjusters. A screw threaded pipe 38 is screwed into the ysocket 39 at the top of the polished rod ad-V juster, and is screwed through the trunnion head 40 from which the trunnions 41 eX- tend. The trunnions 41 are arranged in the usual bearings in the walking beam 42. By lowering the walking'beam to its lowest position, and then Vscrewing down the rod adjusting screw 38, the plunger may be screwed down to the position where it will engage the bolt on the standing valve. A clamping nut 44 may be utilized as desired for indicating the point at which the standing valve will be engaged. In order that the downward movement of the plunger may coincide with the pitch of the threads on the bolt 23, I prefer to have the bolt 23 and screw 38 arranged with threads of the same pitch. Y After the plunger has been screwed onto the bolt, the plunger and standing valve may be lifted through the action of the walking beam so as to iiood the well and clean the pump. Afterward, the standing valve may be lowered in place and the plunger returned to its position and locked in adjustment by a clamping nut 43v on the screw 38, the clamping nut being so located as to indicate the proper position to which the screw should be returned.

I do not claim herein broadly a yielding connection between the standing valve and plunger as this forms the subject matter of application #604,007 filed on even date herewith.
